Answer

\frac{[NO_2]^2}{[N_2][O_2]^2}$$

Here are the equilibrium constant expressions for the given reversible reactions:

*a) For the reaction $\text{N}_2(g) + 2O_2(g) \rightleftharpoons 2NO_2\text{(g)}$ : $K_c = \frac{[NO_2]^2}{[N_2][O_2]^2}$

*b) For the reaction $2N_2(g) + O_2(g) \rightleftharpoons 2N_2\text{O(g)}$ : $K_c = \frac{[N_2O]^2}{[N_2]^2[O_2]}$

*c) For the reaction $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3\text{(g)}$ : $K_c = \frac{[SO_3]^2}{[SO_2]^2[O_2]}$

*d) For the reaction $\text{PCl}_3(g) + Cl_2(g) \rightleftharpoons PCl_5\text{(g)}$ : $K_c = \frac{[PCl_5]}{[PCl_3][Cl_2]}$
